I saw on the film the way they collected the sample in the washbasin. The fact that the sample was collected by wiping both the edge and the plughole is dangerous. You’re likely to find all sorts of stuff in the plughole. However, here is the electropherogram and you can see that the RFU [relative fluorescence unit] value is very high, so the sample is undoubtedly blood, which is the body fluid that provides the greatest amount of DNA. In some cases you see higher peaks of Amanda’s DNA than Meredith’s. Amanda has been bleeding. Nor is it old blood, as the defence might say, because blood decays fast. We have the same result on the cotton-bud box. The light-switch was over-scrubbed, but from the film the way the cotton-bud box was handled was definitely good enough. There too we have mixed blood. So that’s pretty significant for Amanda. Unfortunately for her, she bled at the same time Meredith was bleeding. That’s a lot to explain. [endquote]
The problems previously identified in this argument are that one cannot deduce what tissue type produced DNA from the peak heights (which are typically reported in RFUs) and that one cannot decide when DNA was deposited from the DNA profile itself. However, the issue of where the sampling was done is equally problematic for the prosecution, IMHO. Suppose that Amanda dripped blood on the plug plus or minus a few hours from the time of death. If that were the case, then Colonel Garofano’s other points could be correct, and there would still be an innocent explanation for the DNA. That having been said, I would think that biological matter from brushing one’s teeth or from washing one’s hands is a reasonable explanation for Amanda’s DNA being present.
With respect to your point 3, I have already indicated that Colonel Garofano is a high-profile source of information for the general public in this case. We have heard plenty about Steve Moore from the pro-guilt side of the debate, so what is sauce for the goose is sauce for the gander. I am not calling anyone an idiot; I am saying that Colonel Garofano is wrong.
With respect to point 4, I have a reservation. The jury from the appeal might well interpret this evidence differently from how Massei did; therefore, what Massei said need not circumscribe our discussion. Nevertheless, it might be worth considering. I believe that I have answered all of your questions. Why don’t you quote the relevant passages from the Massei report, and we can discuss them?
